7. Faintness & Confusion With AFib
Like the muscles, the brain must receive an uninterrupted flow of oxygenated blood to do its work. During an AFib episode, blood flow may temporarily or sporadically reduce the amount the brain receives, causing feelings of faintness.
The part of the brain that regulates cognitive skills, the frontal lobe, may respond to a decreased supply of blood by making it difficult to think and solve problems normally, causing confusion. 2’What is Atrial Fibrillation (AFib or AF?)
